Les modes de réalisation de la présente invention concernent un procédé et un appareil de traitement de réseau, un réseau central, une station de base et un support d'informations lisible par ordinateur. Le procédé comprend les étapes suivantes : le lancement par un côté réseau central d'un message de demande de vérification de capacité sans fil de terminal d'interface NG à une station de base principale, le message de demande de vérification de capacité sans fil de terminal d'interface NG comprenant des informations de capacité sans fil de terminal de diverses stations de base auxquelles un terminal accède par l'intermédiaire d'une connexion double ou d'une connexion multiple; puis la réception d'un message de réponse de vérification de capacité sans fil de terminal d'interface NG renvoyé par la station de base principale, le message de réponse de vérification de capacité sans fil de terminal d'interface NG contenant au moins des informations d'indication indiquant si les stations de base prennent en charge un service spécifié. Ainsi, une interaction de message entre le côté réseau central et une station de base permet d'obtenir le scénario d'une prise en charge d'un service spécifié par des stations de base auxquelles un terminal accède par l'intermédiaire d'une connexion double ou d'une connexion multiple, de façon à fournir une commodité à un utilisateur pour sélectionner une station de base correspondante afin de transporter le service spécifié, ce qui permet de garantir l'expérience de l'utilisateur.
